Mattermost-Slack Mirroring Bot

Mirrors chats between Mattermost and Slack, both ways. Written in golang.

Usage

• Create a user for the bot on the Mattermost server, add it to the relevant team.
• Create a bot user for Slack.
• Run the bot:

$ git clone https://github.com/nilenso/mattermost-slack-mirror-bot.git
$ cd mattermost-slack-mirror-bot
$ glide install
$ go build
$ cp config.yaml.example config.yaml
$ # edit the values in config.yaml
$ ./mattermost-slack-mirror-bot config.yaml

• Channels are matched by their names.
• Users are matched by their emails.
• Slack messages posted by the bot appear to be posted by the matching user. But Mattermost messages posted by the bot bear the bot's name.
• The bot joins all public channels on the Mattermost side automatically but on the Slack side you'll need to invite the bot manually to each channel you want to mirror.
• If you invite the bot to a public channel on Slack, it will automatically create and/or join the channel with the same name on Mattermost. The reverse does not happen because bots can't create or join channels on Slack on their own.
• For private groups/channels, you'll need to invite the bot on both the sides to start mirroring.
